2. Front Track Adjustment
Nearly all Post-2005 Kosmic Racing Karts are sold with HST front stub axle, which has a 25mm
stub in order increase the chassis front-end grip or effectiveness. The recommended front width is to
use
3-5mm
spacers
on
the
inside
of
the
hub
(Standard
90mm
HST
Hub).
If the track has less grip a narrow front track will improve the chassis initial reaction, however, this
may cause the chassis to lose performance on longer corners. A track with medium to high grip often
times requires a wider front track width in order to increase the chassis weight transfer. This also
helps the chassis to be more effective on longer corners when more driver input is often times
required to keep the speed up.
3. Rear Track Adjustment
We recommend always starting with the standard OTK 92mm rear hubs. Typically we will start the
rear track at the maximum.
- For the senior divisions this will be 55” and for the junior divisions this will be 53 ½”.
(Measured from outside rear wheel to outside rear wheel) From this point the only real movement is
to narrow the rear track.
- By narrowing the rear track of the chassis while leaving the front track untouched the chassis will
become more effective at releasing the inside rear tyres during cornering. This can initially improve
the chassis performance as well as through the entire corner. However, as grip levels change a
narrow rear track can also create too much ‘Side Bite’ thus, giving the chassis too much grip in the
middle of the corner and decreasing its effectiveness.
It is also recommended when the grip levels are low to test the rear track width narrower due the
potential increase in ‘Side Bite’ from the tyre.
Rear width can sometimes be complicated in regards to the effects it has on the chassis performance,
therefore, make minuet changes when adjusting.
One of the major factors with rear width is chassis balance ‘Feel’. Some drivers do not like to drive
on a chassis with a narrower rear track width, so know your driver.
